Effects of muscular fatigue on knee proprioception during performance and recovery of the knee flexors in physical education males students

الملخص EN

The purpose of this study was to assess the effect of muscular fatigue on the knee proprioception of physical education male students.

Sixteen physical education male students participated in this study from Sport Science College in Mu’tah University.

All students were registered in soccer classes for fall 2008/2009.

Both limbs were used in this study; the dominant limb was used as experimental, and non-dominant limb was used as control one.

Effects of muscular fatigue on proprioception performance was measured by the method of absolute reproduction angular error (i.e.

differences in subject angular reproduction to the angle set by the examiner).

The results indicated that there was no significant difference between the dominant and non-dominant limb before fatigue intervention, p>0.05 also.

indicted that there was a significant difference between the dominant and non-dominant limb after fatigue intervention, p<0.05.

The results also indicted that there was a significant difference between the dominant and non- dominant limb after recovery, p<0.05.

In conclusion, this difference in proprioception between the experimental and control limb will affect the integrity of the knee joint and subsequently cause injury to the lower limb during game at some level.

Therefore, proprioception training program may have a direct impact in decreasing effect of fatigue on the knee joint injuries.
